Present
Today, pearl diving has largely been supplanted by cultured pearl farms, which use a process widely popularized and promoted by Japanese entrepreneur Kokichi Mikimoto. Particles implanted in the oyster encourage the formation of pearls, and allow for more predictable production. Today's pearl industry produces billions of high quality pearls every year. Ama divers still work, primarily now for the tourist industry.
Pearl diving in the Ohio and Tennessee rivers of the United States still exists today. These pearls are called natural pearls, because they are created by nature alone, and are not cultivated by humans. Their shapes are uniquely baroque. Fewer than 1% are found in the classic round shape. They are very rare and are considered collector's items.

Famous quotes containing the word present:
“The at present unutterable things we may find somewhere uttered. These same questions that disturb and puzzle and confound us have in their turn occurred to all the wise men; not one has been omitted; and each has answered them, according to his ability, by his words and his life.”
—Henry David Thoreau (1817–1862)
“Stevenson had noble ideas—as did the young Franklin for that matter. But Stevenson felt that the way to implement them was to present himself as a thoughtful idealist and wait for the world to flock to him. He considered it below him, or wrong, to scramble out among the people and ask them what they wanted. Roosevelt grappled voters to him. Stevenson shied off from them. Some thought him too pure to desire power, though he showed ambition when it mattered.”
—Garry Wills, U.S. historian. Certain Trumpets: The Call of Leaders, ch. 9, Simon & Schuster (1994)
“I fear ... that both dictators [Hitler and Mussolini] think their present methods are succeeding because of the gains they have made in Albania, Hungary and Yugoslavia.”
—Franklin D. Roosevelt (1882–1945)
